Mystery Notification Icon

[MrsLee]

Can anyone please tell me what this pain, old fashioned, white keyhole notification is? It keeps popping up in the corner of my Samsung Galaxy SIII. I'm locked out of my phone, otherwise, I'd just pull down the status bar to see what app it belongs to. I'm wondering if it's the reason I'm locked out of my phone? I attached a picture of the icon. Can someone please tell me what app this notification belongs to please??? I've never seen it before... Thank you

This looks like the notification icon I get when I'm signing in to a new device or browser, prompting me for approval for that device or browser to sign in to my account. It's related to two-factor authentication.

Sadly, I JUST got this today but I didn't really pay attention to the notification icon as it now pops full-screen when I unlock my phone.

Google. I'm not 100% certain but it's likely part of the Play Services framework, maybe rolled into the Google app.
